The review highlights the electroanalytical methods used for the determination of the artificial dyeSunset Yellow, one of the most frequently used azo–dyes, with a very wide field of the applicationduring the last two decades. As azo–dyes may have detrimental effects on living organisms, theircontent in food must be strictly controlled. Despite other analytical methods for determination of azo–dyes, the electroanalytical methods, especially voltammetric methods, offer many other advantagesbesides high sensitivity, selectivity, and reproducibility – e.g., less time for sample preparation anddetermination, low investment and running cost, electrode miniaturization and modifications, as wellas use of eco–friendly materials. This critical review focuses on the electrode materials and theirmodifications since they are the deciding factor for a successful voltammetric determination of SunsetYellow. In addition to this, the reaction mechanisms for determination and analytical performance arealso presented in the paper.
